Free Flow is a mentally stimulating game that keeps you playing as the levels gradually grow more complex as the boards extend and the colors multiple. Although, this game will drive you absolutely nuts.
The game starts off with 5×5 and 6×6 game boards, which is not challenging. As the game progresses, the boards expand with larger 7×7, 8×8 and larger boards. With the extra space comes more colors that need to be connected. If you get bored of simply solving the puzzles, you can play a time-trial mode to see how many you can solve in a specific amount of time.
The goal of this game is to swipe the screen to connect matching colors with a pipe to create a flow. Pair all colors to cover the entire board to completely solve each puzzle. But be careful, pipes will disconnect if they overlap.
